TONEWINNER AD-1PA+ BLACK/SILVER JAUDAS PASTIPRINĀTĀJS (cena par gab.)

AD-1PA+ is a Hi-Fi stereo amplifier with Class A/AB mode, high power transformer, transistors and capacitors. It’s a flagship amplifier which can be perfectly connected with AD-1PRE+ processor. As a top 10 audio brand in China, Tonewinner has 30+ years experience in designing and manufacturing acoustic products. As an original supplier, Tonewinner always warmly welcomes distributors, partners and customers around the world.

Main Features

• Class A circuit that adopts full balance, full symmetry, differential input to differential BTL power output.
• Both left and right channels adopt independent power supply, which boost the channel seperation to the highest degree.
• Output power 300W/8Ω each channel. It uses 1,200W high quality toroidal transformer and audio special capacitor up to 180,000uF. It also uses high power transistors to parallel output, offering 60A current output.
• High end aluminum chassis, rigorous intenal layout, and strong anti-interference ability.
• Specially gold plated IC socket for audiophiles to replace operational amplifier.
• lt adopts Tonewinner's patented technology: High/low voltage power supply intelligently switch management. It can meet the needs for Hi-Fi Class A power output, and also conforms to energy conservation and environment protection concept (patented number: ZL201420783891.8).
• Multiple circuit protection: short circuit protection, overheating protection and DC protection.
• It adopts Tonewinner's patented technology: ~110-115V/~220-230V power supply auto-switch(patented number: ZL.201420543195.X).

• Front panel indicating functions: Standby/ON/Protection.~110-115V/~220-230v power supply auto-switch.

A Class A amplifier as powerful as it is efficient

The amplifier stage of the Tonewinner AD-1PA+ embeds 8 pairs of high power transistors TTC5200 and TTA1943 within a Class A. These allow the amplifier to deliver a consequent power of 300W RMS per channel under 8Ω.

Class A/AB switch

The Tonewinner AD-1PA+ has three operating modes: Class A, Class AB or Auto. A switch allows you to select the most suitable mode according to your needs and your installation. The Auto mode automatically switches from Class A to Class AB when the temperature of the unit reaches a certain limit and switches back to Class A if the temperature drops.

Bi-wiring possibility

With its dual speaker terminals, the Tonewinner AD-1PA+ offers the possibility of bi-wiring. This method of connecting to speakers can offer an improvement in sound quality by reducing the magnetic interactions of the cables.

A large power supply

In order to deliver such a power, the Tonewinner AD-1PA+ is equipped with a large power supply, including a high performance toroidal transformer of no less than 1200W. 16 large filter capacitors with a total capacity of 180,000µF ensure a clean and stable electrical signal. In addition, the left and right channels are independently power supplied.

Perfect isolation

The internal design of the AD-1PA+ has been thought to physically separate the different sections of the device and thus ensure a very good isolation. This design effectively limits interference and noise.
